Importance of optimizing other design factors In this technique, consideration has been given to the choice of impression material as well as to the design of the impression tray to minimize the amount of pressure exerted on flabby tissue. Extent of flabby tissue 3.  |  From time immemorable there have been different theories that had been advocated. Ø Milo V. Kubalik and Bert C. Buffington developed this technique the objective of which was to reduce the stress on any given tissue by increasing load bearing area. The … This site needs JavaScript to work properly.

Conventional mucostatic methods like employing a window tray technique, multiple relief holes, or double spacers can be employed when the flabby tissue is localized. The full text of this article hosted at iucr.org is unavailable due to technical difficulties. What is an impression? HHS Mucostatic theory follows the impression being taken of the mucosa when in its normal resting position. Gen Dent. This self retention ruled out finger pressure during impression making, helping to achieve mucostatics. Various techniques have been proposed to record a desirable impression. Additional retention is achieved by using perforated trays. When utilizing this concept (mucostatic impression technique), double spacers, multiple relief holes, or a window tray technique has been used where the flabby tissue is located (MacEntee, 1996, Boucher, 1951, Klein and Broner, 1985, Hyde et al., 2008, Devan, 2005, Zinner and Sherman, 1981). Improved digital impressions of edentulous areas. the form of the tissue is recorded vertically and laterally, when a controlled partial vacuum is established in impression tray specially built for the patient. Clipboard, Search History, and several other advanced features are temporarily unavailable. Treatment: 1. alveolectomy to reduce the sharp process 2. relief for the knife-like ridge area 3. construction of denture having resilient lining. Complete denture fabrication in clinically compromised situations such as flabby ridges is a challenging task for the clinician. The choice of impression techniques depends on MUCOSEAL TECHNIQUE :- • Stated by Pryor, 1948 • Introduced as a variation to mucostatic technique • Anterior lingual border molded by the floor of the mouth with the tongue in repose • Tray extended horizontally backward, over sublingual glands towards the tongue to achieve a border seal • Benefit of minimal pressure, provides maximum extension of denture borders & maximum denture … The Principles of Functional and Mucostatic Impressions for Complete Denture Bases: A Review. Two-step mucostatic impression techniques produced less … Inspect the impression to determine if it is acceptable. 45.6% used Selective pressure technique for making final impression, while 32.0% used Mucocompressive technique and 22.3% mucostatic technique. • 1936 Alginate-type materials patent awarded. considerations was given emphasis for the functions of retention, stability and comfort of complete denture. Patient’s requirements 2. Please check your email for instructions on resetting your password. In the case of silicone impression materials in particular, there are a number of impression techniques that can be employed. The mucostatic impression techniques generated less soft tissue displacement than the mucocompressive technique. The technique for insertion of the impression into the mouth involves ‘puddling’ the impression into place. 5 They introduced a modeling plastic, a method for manipulating it and a technique that is said to have been the first to utilize the entire denture bearing area for denture retention.They were the first to teach the closed mouth all modeling plastic technique called the Greene Brothers all compound impression. The muco-dynamic on the other hand is a close mouth impression technique that allows the patient the full freedom and range of movements (Fig. The shortcomings of this principle gave rise to the mucostatic technique by … In cases where the impression is made from a hydrophobic material the hydrophilic slurry of calcium sulphate hemihydrate in water may not be able to approach closely enough to the surface of the impression (on a … However, the search did not reveal any RCTs or clinical trials on the topic. Mucostatic technique enabled a satisfactory recording of ridge hyperplasia by avoiding overcompression of the tissues. His technique consisted of making a mucostatic impression of the edentulous ridges followed by a pick-up impression with digital compression of the first through holes prepared on the impression stock tray. Impressions can also be described as mucostatic or mucocompressive, being defined both by the impression material used and the type of impression tray used (i.e. 9. As the name signifies Muco static means no pressure is applied On the tissues while taking Impression. 6. Additional retention is achieved by using perforated trays. In this paper, the authors have proposed a newer technique of impression making of the flabby tissues using a combination of readily available newer and older materials to ensure an accurate and easy impression of these tissues. spaced or closely adapted).Mucostatic means that the impression is taken with the mucosa in its normal resting position. His technique consisted of making a mucostatic impression of the edentulous ridges followed by a pick-up impression with digital compression of the first through holes prepared on the impression stock tray. 10. impression technique: 1. Addison 1 credits Page 2 with introducing the mucostatic technique. Fabrication of a new set of maxillary and University, Varanasi, India. • 1950s elastomeric impression [Primary mucostatic impressions for removable complete dentures]. These impressions will generally lead to a denture which has a good fit during rest, but during chewing, … Zinc oxide Eugenol is the impression material of choice . spaced or closely adapted).
